Open Access DOI:10.23937/2572-4061.1510026 Siva K Nalabotu, Nandini DPK Manne, Madhukar B Kolli, Geeta Nandyala, Radha K Para, Kevin M Rice, Cynthia B Jones and Eric R Blough Article Type: Research Article | First Published: July 04, 2019 Inhaled cerium oxide (CeO2) nanoparticles have been shown to be capable of translocation to the liver where they can cause dose dependent toxic effects. Herein, we investigate if the deposition of cerium in the liver is linked to increased oxidative stress and cellular apoptosis. Specific pathogen free male Sprague-Dawley rats were instilled with either vehicle (saline) or CeO2 nanoparticles (7.0 mg/kg) and euthanized 1, 3, 14, 28, 56, or 90 days post exposure. Liver samples were evaluated for e...

Open Access DOI:10.23937/2572-4061.1510024 Effects of Fumes Inhaled from Cooked Meat Shivam Joshi, MD Article Type: Review Article | First Published: June 14, 2019 Since 2015, the World Health Organization has regarded the ingestion of processed meat as a definite carcinogen and red meat as a probable carcinogen, basing their recommendations on studies showing an increased risk of colorectal cancer. The findings have led many to limit their ingestion of red and processed meat. Over the past several decades, a growing body of literature has formed regarding the possible harmful, if not carcinogenic, effects of fumes emanating from cooked meat on humans. In ...

Open Access DOI:10.23937/2572-4061.1510016 A New QSAR Model for Acute Fish Toxicity based on Mined Structural Alerts Giuseppina Gini, Thomas Ferrari, Anna Lombardo, Antonio Cassano and Emilio Benfenati Article Type: Research Article | First Published: January 14, 2019 In this paper we discuss the problem of predicting the fish toxicity property of chemical compounds, and show how this can be approached using a computational intelligence method. There are two views on assessing toxicities: One says that such properties can be derived from the whole molecular structure, the other that some specific functional substructures, called Structural Alerts (SA), are able to explain the toxicity. In this work, a new Structure-Activity Relationship (SAR) approach is prop...

Open Access DOI:10.23937/2572-4061.1510014 Exposure and Risk Assessment of Selected Chemical Hazards in Cabbage and Lettuce Isaac W Ofosu, Samuel Akomea-Frempong, Emmanuel De-Graft J Owusu-Ansah and Godfred Darko Article Type: Original Research | First Published: November 26, 2018 Many health-conscious consumers are increasingly making deliberate choices for plant-based diets because probably they think they were safer. Majority of these consumers who dwell in cities therefore demand leafy vegetables for their daily consumption. The demand has created the opportunity for many urban dwellers to join the business of vegetable cultivation using every space available. Urbanization is associated with industrialization, and with it comes the attendant anthropogenic hazards. Sub...

Open Access DOI:10.23937/2572-4061.1510013 A Review of Environmental Contamination by Organochlorine and Organophosphorus Pesticides in Egypt Farag M Malhat, Naglaa M Loutfy, Sara M Greish and Mohamed Tawfic Ahmed Article Type: Review Article | First Published: November 26, 2018 All pesticides are potentially toxic to all sorts of life and some are even classified as probable human carcinogens, neutrotoxics and endocrine system disruptors. The toxicity level of a pesticide depends on the lethal dose (LD) of the chemical, the length of exposure, and the route of entry or absorption by the body. There are many different pesticides in use today with very different modes of action and levels of toxicity. To protect the public, WHO has developed a hazard classification syste...

Open Access DOI:10.23937/2572-4061.1510011 Lawrence V Tannenbaum, David M Bullis, Nicholas R Deuel, L Mike Conner, Michael J Chamberlain and Karl V Miller Article Type: Research Article | First Published: June 30, 2018  Ecological risk assessments (ERAs) for contaminated terrestrial sites regularly include mammals as receptors-of-concern whose home ranges dwarf the sites by tens of times. As a consequence, opportunities to sustain chemical exposures of concern are greatly limited. In having notably miniscule densities as well, wide-ranging mammals are poorly selected species to evaluate because true populations are effectively non-existent at sites. Collectively...

Open Access DOI:10.23937/2572-4061.1510001 Carla Falugi, Chiara Gambardella, Tommaso Bonfiglio, Zoltan Rakonczay, Federico Biggi, Sara Novelli and Mariangela Masini Article Type: Original Article | First Published: August 26, 2015  Even though the adverse effects on environment and organism health have been long and thoroughly studied, the problem represented by the continuous use of neurotoxic pesticides, in particular organophosphates (OPs, organic salts of the pyro phosphoric acid), is still open. These are considered as emerging pollutants, as their massive employment is relatively recent, dating after the ban of persistent organic pesticides. OPs are not persistent for...
